## What is CVE-2017-12718?

CVE-2017-12718 is a high-severity memory corruption vulnerability in Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump, published on 15 Feb 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

A Classic Buffer Overflow issue was discovered in Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump, Version 1.1, 1.5, and 1.6. A third-party component used in the pump does not verify input buffer size prior to copying, leading to a buffer overflow, allowing remote code execution on the target device. The pump receives the potentially malicious input infrequently and under certain conditions, increasing the difficulty of exploitation.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer), CWE-120 (Buffer Copy without Checking Size of Input)

Check this codebase for CVE-2017-12718 and fix it if it is affected.

What it is: CVE-2017-12718 is a high-severity memory corruption vulnerability in Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump, published on 15 Feb 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-12718 in the wild and no public exploit code.

Affected product: Smiths Medical Medfusion 4000 Wireless Syringe Infusion Pump. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
